Comparison of Different El Niño and La Niña
|While El Niño
and La Niña are often associated with consistent climate
anomalies throughout the globe, differences in the tropical SST
pattern, basic atmospheric state over the globe and "random"
climate variability mean that the climate anomalies may not be the
same from event to event. These plots give an indication of how
similar and how different the atmosphere can be during

OLR is a measure of cloudtop temperature. Where the
temperature is low, the cloudtop is high indicating the presence of
"convection" (precipitation) in the region.
Data are averaged over 10N to 10S.
